Hillary Lives

This column was written by CBS News Early Show co-anchor Harry Smith.

"So what?"

That's what a lot of Barack Obama's supporters are saying this morning. So, Hillary Clinton won in Pennsylvania. She won by ten percentage points. And they'll say yeah, but she was up by 20 percent not so long ago.

Hillary Clinton is not going away, and her ten-point win was exactly what she needed to stay alive. What happens next is crucial. Let's say for argument's sake that Senator Clinton keeps it close in North Carolina on May 6. And what if -- that is a big what if -- she wins in Indiana that same day.

Indiana sits right next door to Illinois, Obama's home state. That helped Obama a bunch in Iowa. If Hillary can show she can win on his turf, then she has a pretty compelling argument to super delegates. She will point to California, Ohio, Pennsylvania, and Texas, and say, "Big states. I can win there."

And momentum? She'll have it. A lot can happen in two weeks. This thing isn't over yet, not by a long shot.
